Zusammenfassung:The embodiment discloses a small coal pillar gob-side entry driving prevention and control method for complex disasters of a large-dip-angle coal bed, and relates to the technical field of coal mining. According to the technical scheme, the small coal pillar gob-side entry driving prevention and control method for the complex disasters of the large-dip-angle coal bed comprises the following construction steps that S1, the position of a driving roadway is determined; S2, an upper-bottom lower-top roadway layout form is formed; S3, the rock burst is prevented and controlled, a stress distribution curve is independently worked out according to the factors such as the coal-rock structure, geological structure and the like of a working face, stress under all influence factors is superposed, andfinally, and whether or not a rail trough is a strong impact dangerous area is finally determined according to the danger level, evaluated according to multiple factors, of the rock burst; and S4, technical management of cha
